I just got an equation which governs the electron emission of a hot body. That is the so call Richardson equation : I = A T^2 exp(-b/T), where A and b are the two constants. [I] = ampere/cm^2. I used this formula and assumed that the emission area of a tungsten cathode in a television is around...
I am a novice, then I care about some free codes for students. I am caring about some code to compute reactor physics like neutron distribution, lattice calculation, thermohydro calculation ... Thanks for the above news, anyway.
Thanks berkeman,
Here is a link mentioned the pA of the currents: http://www.coursework.info/i/172.html [Broken]
I agree with you that a CRT needs lead mixed glass envelope to shield the EM radiation. I went through the link you gave but it seems that the mentioned few mA current is the...
Thanks ,
But I still have a doubt about the number of few mA current. Since this few mA current is actually can produce a considerable bunch of bremstralung rays when the hit the phosphorus coated screen, so harful to the audiences. So if you or anyone has some specifications of a tv from the...
Hi ,
I have a wonder about the real size of a tivi (sony, toshiba...) e-gun, how it works and what's the maximum e-current of it ? Please tell me something about it.
